Transmission & Distribution System Analysis

Transmission and distribution businesses are continually facing new challenges in balancing their increasingly technical complex assets against the need for improving economic efficiency. This demands expertise of the highest level to bring about targeted developments whilst also striving to improve overall service levels. Our consultants have assisted numerous such businesses with power systems worldwide with wide ranging services, from short-focused to extended planning studies. Their consulting assignments have included the following specialist areas:

• Steady state analyses for development or operation optimisation including calculations of equipment overloading, voltage levels, short-circuit (fault) levels.

• Dynamic analyses including angle and voltage stability.

• Impact of new or modified generation.

• Reactive compensation equipment design including SVCs, Statcoms, series compensation, shunt banks.

• Power quality studies.

• Protection relays co-ordination.

• Plant and load modelling.

HVDCHVDC transmission has been in commercial operation for over 50 years, although up until recently confined to a relatively small number of locations. However, recent years have seen a rapid expansion of the use of HVDC, partly as a result of the emergence of new technologies. It is now an accepted option for transmission where its technical characteristics can mean either that it is the only available option, or that it offers distinct advantages over conventional AC transmission and is now also making in-roads into distribution. Our consultants have carried out numerous studies in the following areas:

• Application of large ‘conventional’ current-sourced-converters (CSCs) for point-to-point transmission between separate AC systems and embedded within the same AC system.

• Use of CSC HVDC as an alternative to AC transmission developments.

• Use of the more recent voltage-source-converters (VSCs) in connecting offshore wind-farms and oil production platforms.

• Analysis of multiple VSCs and CSCs within a relatively small geographic area.

• Grid Code compliance studies including identification of non-compliance risk Identification of the requirement or benefit of supplementary converter controls.

Basic CSC HVDC configuration


GenerationAdditional generation is often the main driver for many of the studies identified above for ‘transmission & distribution system analysis’. However, sometimes a more detailed study of the generation itself and its effect on the local network is required. Our consultants have carried out several such studies in the following areas:

• Compliance studies to ensure all requirements of the Grid Code can be met, including identification of reactive compensation as required.

• System analysis on the network connecting to the transmission/distribution system to ensure all equipment operates within its continuous and short-circuit ratings and acceptable voltages for all generator operating modes including tap-changer settings.

• Dynamic analysis of the effects of local and more remote faults to ensure specified performance can be achieved.

• Detailed modelling of the generator and its controls, including adjustment of model data to ‘line-up’ with actual test results.

RenewablesThe renewables market place is one that is continuously growing and faces many challenges. In order to accommodate such developments, distribution networks are likely to need to transform their passive networks into actively managed networks on an economic, efficient and coordinated basis. Penetration of distributed generation has already started to pose a number of technical issues. These issues include voltage regulation, fault levels and impact on existing fault levels, reactive power compliance, transient stability, harmonics, protection coordination, automation and telecommunications, transient disturbances and stability of distributed generation, energy storage etc.

S&C Electric can assist sustainable energy developers in the initial grid connection feasibility stage of their scheme. The aim of the grid connection feasibility study is to identify potential grid connection options along with indicative connection costs associated with these options. S&C has extensive experience dealing with distribution network operators and in managing the grid connection application process for wind farm, Solar PV farms and Biomass Plants etc. connected at distribution and transmission level.

Industrial Networks including Marine & OffshoreImproving the reliability and efficiency of electrical power supplies have become a major challenge due to the increased complexities of industrial and commercial operations requirements and plant processes. An important factor in achieving these objectives is the effective application of automation and control technologies into industry and commerce. Furthermore, changes to industrial networks can require just one, a few or several different types of studies to ensure all relevant factors are duly considered.

The different types of industrial networks we have worked with include:

• Oil & Gas onshore and offshore

• Marine

• Naval

• Land-based industrial complexes including pharmaceuticals, metals etc.

Our consultants have carried out numerous studies in the following areas:

• Power system design concept and control philosophy.

• Power (Load) Flow: Equipment ratings, Contingency analysis, Grid interface real and reactive power flows, Power factor correction

• Short-Circuit (Fault-Levels): Equipment ratings, means of reduction, protection study information

• Stability and reliability evaluation: Loss of synchronism, Blackout recovery, Automatic load shedding scheme design

• Motor-starting: Voltage dip, Run-up time

• Protection: Design and coordination

• Distorting Loads: Harmonic penetration, Filter design, Flicker

• Techno-economic Evaluation: Cost minimisation

• Tendering, equipment specifications, inspection and witness testing

• Project supervision

• Diagnostic studies: system and plant failure investigations


Although the Power Systems Services group within S&C Electric Europe was only formed during the first half of 2011, our team of consultants have carried out a large number of system analysis investigations whilst at previous companies.

The following is a list of the key projects covering just the last 7 years which the consultants either carried out solely or had the major input.

Serge KabundaSenior Consultant


Sarat C. Vegunta has over 6 years experience in providing power systems consultancy and R&D services. He has over 2 years experience as a consultant at TNEI Services Ltd. in providing power systems consultancy services to the renewable, transmission, distribution and industrial sectors; and over 4 years R&D experience as part of his doctoral studies at the University of Manchester in the UK, undertaking research in the fields of power systems, power quality and utility-industrial distribution systems/equipment.

He received his Bachelor Degree in Power Electronics in 2002 at Nagpur University, India. He furthered his education by completing a MSc degree in Power Systems 2004 at University of Manchester, UK. Following this he has undertaken research completing his PhD degree in the fields of Power Systems and Power Quality at University of Manchester, graduating in 2008.

As part of his role as a Technical Consultant and subsequently as a Senior Consultant at TNEI, he has undertaken a broad set to power systems and power quality studies, and has been instrumental in developing TNEI’s capability to undertake insulation co-ordinations studies for wind farms. During this period, he has undertaken several high-level and complex power systems and electrical design studies for wind farms.

Some of these studies include: conducting high-level load-generation grid connection feasibility and estimating related connection charges; detailed load flow, fault level, harmonic analysis, and grid-compliance studies; updating utility network model; detailed power quality studies, including motor start, transformer inrush, flicker assessment and electrical system harmonic assessment and modelling; conducting wind farm insulation co-ordination studies for lightning and switching surges, etc.

As part of his doctoral studies, he has undertaken a major research project at the University of Manchester working with one of the Europe’s largest pharmaceutical companies and on EU ‘RISE’ and ‘DG FACTS’ projects, understanding the impact of voltage sags on continuous manufacturing processes and related equipment. He was instrumental in developing a procedure for estimating the cost of down time, allowing companies to develop systems to shore up the gaps and avoid potential and costly problems. The procedure establishes the cost accrued due to process down time depending on the time of day. The procedure and resulting information was fed back to the plant engineers to allow them to manage and optimise process scheduling to minimise impact.

Work undertaken during his doctoral studies was published in journal proceedings and was presented at industrial conferences. Work during this period has also contributed towards CIGRE/CIRED/UIE JWG.1.110 (C4.1.10 and C4.1.07) report ‘Voltage Dip Immunity of Equipment Used in Installations’ and technical reports of European Union-funded ‘RISE’ and ‘DG FACTS’ projects.
